例句

Alternatively, like allopolyploids, they may arise by the nondisjunction of chromatids during the mitotic division of a zygote.

與異源多倍體相似的是，它們也是在有絲分裂中合子的染色單體不分離形成的。

At anaphase I and telophase I, chromosome nondisjunction and degenerated spindle formation resulted in multiple uneven spore production.

在減數分裂后期I和末期I，染色體不進行分離以及紡錘體不能形成而導致來多個不均等的孢子的產生。

Autopolyploids may arise from the fusion of diploid gametes that have resulted from the NONDISJUNCTION of chromosomes at meiosis.

同源多倍體通常可能來自在減數分裂過程中染色體不分離導致的二倍體融合。
